Field Detail

s

protected Sample s

The sample whose data is being displayed.

row_min

protected int row_min

The first row of the dataset. Default is 0.

See Also:

row_max, Year.row()

row_max

protected int row_max

The last row of the dataset. Default is -1, so if row_min and row_max are never set, no rows are displayed.

See Also:

row_min, Year.row()

ZERO

protected static final Integer ZERO

Constructor Detail

DecadalModel

public DecadalModel()

Default constructor. Not used, but required for subclassing.

DecadalModel

public DecadalModel(Sample s)

Constructor, given a Sample.

Parameters:

s - the Sample whose data is being viewed

Method Detail

getSample

public Sample getSample()

getColumnName

public String getColumnName(int col)

Return the column name. The first column is "Year", the last column is "Nr" (number), and the 10 columns in between are 0 through 9.

Overrides:

getColumnName in class AbstractTableModel

Parameters:

col - the JTable column number to query

Returns:

the column's name

countRows

protected void countRows()

getRowCount

public int getRowCount()

Return the row count. For the Data tab of a Sample (i.e., not Weiserjahre), it adds an extra row if the last datum is a -9 year, thus ensuring that there's always one blank after the end for user editing.

Overrides:

getRowCount in class AbstractTableModel

Returns:

the number of displayable rows

getColumnCount

public int getColumnCount()

Return the column count. This is always 12: the decade, 10 columns of data, and the histogram cell

Overrides:

getColumnCount in class AbstractTableModel

Returns:

the number of columns, 12

getYear

public Year getYear(int row,
                    int col)

Return the Year that a (row,col) cell should display. This method creates a new object, and is called far, far too often. For opening one raw sample, it creates 526 Year objects, and about as many each time the window is uncovered (and there are only about 200 years of data visible!). This can't be good for performance. Make sure each call to this is really needed, or make them not require object creation each time. (Candidates for this: 2 calls in getValueAt().)

Parameters:

row - the row in question

col - the column in question

Returns:

the Year that the (row,col) cell should display

getMean

protected final Integer getMean(int row)

getValueAt

public Object getValueAt(int row,
                         int col)

Overrides:

getValueAt in class AbstractTableModel

getColumnClass

public Class getColumnClass(int col)

Return the Class of the specified column. This is Integer.class for the displayed data, else String.class

Overrides:

getColumnClass in class AbstractTableModel

Parameters:

col - the column to query

Returns:

the column's class

isCellEditable

public boolean isCellEditable(int row,
                              int col)

Overrides:

isCellEditable in class AbstractTableModel

setValueAt

public void setValueAt(Object value,
                       int row,
                       int col)

Overrides:

setValueAt in class AbstractTableModel
